Lavandula plant named ‘BKLVSTFPU’

ABSTRACT

A new and distinct cultivar of  Lavandula  plant named ‘BKLVSTFPU’, characterized by its compact and broadly upright plant habit; freely branching growth habit; early and freely flowering habit; purple-colored flowers with violet-colored bracts arranged on terminal spikes; and good garden performance.

Botanical designation: Lavandula stoechas.

Cultivar denomination: ‘BKLVSTFPU’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Lavandula plant,botanically known as Lavandula stoechas, commonly referred to asLavender and hereinafter referred to by the name ‘BKLVSTFPU’.

The new Lavandula plant is a product of a planned breeding programconducted by the Inventor in Maasdijk, The Netherlands. The objective ofthe breeding program was to develop new compact and early-floweringLavandula plants with good performance and attractive plant form andflower coloration.

The new Lavandula plant originated from an open-pollination in July,2012 of a proprietary selection of Lavandula stoechas identified as codenumber 4300112, not patented, as the female, or seed, parent with anunknown selection of Lavandula stoechas as the male, or pollen, parent.The new Lavandula plant was discovered and selected by the Inventor as asingle flowering plant within the progeny of the stated open-pollinationin an outdoor nursery in Maasdijk, The Netherlands in July, 2013.

Asexual reproduction of the new Lavandula plant by terminal cuttings ina controlled outdoor nursery environment in Maasdijk, The Netherlandssince September, 2013 has shown that the unique features of this newLavandula plant are stable and reproduced true to type in successivegenerations.

SUMMARY OF THE INVENTION

Plants of the new Lavandula have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature and light intensity, without, however, any variancein genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of the new Lavandula plant. Thesecharacteristics in combination distinguish ‘BKLVSTFPU’ as a new anddistinct Lavandula plant:

-   -   1. Compact and broadly upright plant habit.    -   2. Freely branching growth habit.    -   3. Early and freely flowering habit.    -   4. Purple-colored flowers with violet-colored bracts arranged on        terminal spikes.    -   5. Good garden performance.

Plants of the new Lavandula differ primarily from plants of the femaleparent selection in the following characteristics:

-   -   1. Plants of the new Lavandula are more compact than plants of        the female parent selection.    -   2. Plants of the new Lavandula have broader inflorescences than        plants of the female parent selection.    -   3. Plants of the new Lavandula and the female parent selection        differ in flower color as plants of the female parent selection        have dark pink-colored flowers.

Plants of the new Lavandula can be compared to plants of the Lavandulastoechas ‘Bee Happy’, disclosed in U.S. Plant Pat. No. 12,573. Inside-by-side comparisons, plants of the new Lavandula differ primarilyfrom plants of ‘Bee Happy’ in the following characteristics:

-   -   1. Plants of the new Lavandula are more compact and shorter than        plants of ‘Bee Happy’.    -   2. Plants of the new Lavandula and ‘Bee Happy’ differ in flower        color as plants of ‘Bee Happy’ have purple-colored flowers with        white-colored bracts.

DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photographs and following detaileddescription were grown in 12-cm containers during the spring and earlysummer in a glass-covered greenhouse in Maasdijk, The Netherlands andunder cultural practices typical of commercial Lavandula production.Plants were pinched one time and were 23 weeks old when the photographsand description were taken. During the production of the plants, daytemperatures ranged from 15° C. to 22° C. and night temperatures rangedfrom 12° C. to 16° C.
